auto-deletes from the system
counting…on Sep 3, 2026

An official fix is available, so this entry is kept for 30 days and then removed automatically.

01

Who is affected

Linux kernel 6.12 and earlier versions that include the RDMA/siw driver without the sendpage_ok() check. Typical users are system administrators running RDMA‑enabled workloads.

02

Real-world impact

An attacker could crash the system or potentially execute arbitrary code by sending crafted RDMA messages that trigger the splice page warning.

03

Why this severity

The CVSS score of 9.8 reflects that the vulnerability is exploitable over the network with no authentication or user interaction, and it can compromise confidentiality, integrity, and availability.

04

What to do about it

official fix available
recommended steps
  1. 011. Update the Linux kernel to a version that includes the RDMA/siw sendpage_ok() patch (e.g., the latest 6.12.x or newer).
  2. 022. Reboot the system to load the updated kernel.

NVD description indicates the issue has been resolved in newer kernel releases.
